ROTARY ASH-SIFTERL SPECIFICATION forming part of Letters Patent No.634,263, dated October 3, 1899.

Application filed September 23, 1898. Serial No. 691,703. (No model.)

To all whom it may concern."

Be it known that I, ADOLPH HAENICHEN, a citizen of the United States,residing in Paterson, county of Passaic, and State of New Jersey, haveinvented certain new and useful Improvements in Rotary Ash-Sitters; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification. This invention relatesto rotary sitters for coal, ashes, flour, &c.; and it constitutes animprovement upon the sitter shown and described in Letters Patent No.588,745, granted to me August 24, 1897.

The invention consists in the improved rotary sitter and in thecombination and arrangement ot the various parts thereof, substantiallyas will be hereinafter more fully described, and finallyembodied in theclauses of the claim.

The invention is fully illustrated in the accompanying drawings, inwhich like letters of reference indicate parts correspondingly referredto in this specification, and wherein- Figure 1 is a view in sideelevation of my improved rotary sitter in position upon the top of abarrel or other receptacle, certain parts being broken away. Fig. 2 is aview in elevation of the sitter as shown in Fig; 1, certain parts beingbroken away; and Figs. 3, 4, and 5 are enlarged views of certaindetails-of my invention.

In said drawings the sitter is shown as consisting, essentially, of arotary cylindrical sitter, a box provided with a cover and in whichsaidsitter is revolubly mounted, and a support for sustaining said box upon.a barrel, can, or other receptacle. Thesupport consists of foursegment-shaped pieces a. a b b, preferablyof wood,two of themtorinstance, a cU-having their tips removed and being secured to the othersby means of screwsc, pros jecting through the tips thereof and into theends of the first-named pair. The box d is preferably rectangular inshape and has two opposing sides, as 61 d inclined toward each other. Itmay be secured upon the support in any desired manner, as by screws.

2 indicates a cover for the box, and it con-' sists of the side plates6' c connected by. the strips f f The strips f f connect the side platesnear the lower edges of the latter, and connecting their upper edges andextending over the upper edges of the side plates is a galvanizedsheet-iron hood g, secured to said strips and the side plates by screwsor nails g. The cover is pivotallymounted on the box by means of hingesh, whose leaves are arranged and move in parallel planes, be ingtherefore secured to the sides of the cover and the box, and means forholding the cover tightly down upon the upper edges of the box consistsof apair of clips i, secured one upon each side plate of the cover andeach having a slit z" at its lower end, which biturcates the clip, andbeing adapted to receive, when the coveris in its lowermost position, asecuring thu inb-screwe having a shoulder 1' which when said thumb-screwis screwed inwardly abuts against the face of the clip each side of theslit thereof.

indicates a litter secured to the front strip f The sifting deviceconsists of two circular side or end pieces Z, connecting and securedaround the peripheries or edges of which is a wire screen m, formingtherewith a cylinder.

, Each side or end piece Z has an outer peripheral flange Z, and betweenthe two flanges of said side or end pieces is arranged the screen. Theends of said screen are secured down upon the peripheries of the side orend pieces by means of surrounding strips n, secured to the latter byscrews or nails 'n, projecting through meshes ot the screen, or, ifdesired, the parts referred to may be held together by simply punchingthe strips downwardly into the wood of the side or end pieces betweenthe meshes ot the wire, also using but comparatively few nails orscrews.

The cylinder is divided longitudinally to form a comparatively smallportion 0, which is hinged to the main body of the cylinder by hinges o,substantially similar to the hinges h. The portion 0 of the cylinder issecured down to the main body thereof by means of a pair of hooks 17,one 011 each side of the cylinder,each engaginga pinp,projecting fromthe main portion of each end piece of the cylinder, said hooksconstituting the downwardlybent free end of a rock-shaft preferably ofheavy wire, extending over the portion 0, fulcrumed in recesses r in theflanges Z and held in place by the strips 12, which latter are bent topass over them. The rock-shaft is formed intermediate its ends with abend s, which forms a handle by which the hooks are manipulated.

The means for revolubly mounting the cylindrical sitter proper in thebox consists of a pair of disks .2, provided with stub-shafts .2 .2projecting from their outer faces and secured to the outer faces of theside or end pieces of said cylinder. The stub-shaft a has a squared end2 upon which is mounted a crank .2 having a handle .2 by which rotationis imparted to the cylinder.

In Figs. 3 and 4C is shown in detail the construction of thecylinder. Itwill be seen that at the meeting edges of the two portions of thecylinder are arranged cross-rods or heavy wires i, which connect thecorresponding parts of the side or end pieces and around which arefolded the screen 177 and the strips 12, the former being bent back uponitself, as shown at 11, Figs. 3 and 4, and the ends of the latterextending over and being secured to the adjoining edges of said parts ofthe side pieces and secured thereto by means of nails or screws r. As ameans for keeping the support and the sifter generally in properposition on the barrel 1 have provided angular lugs '20, secured to theunder side of the support by screws 0;, which, if it is desired to mountthe sifter upon barrels or other receptacles of different diameters, mayproject through longitudinal slots 3 in said lugs.

Having thus fully described myinvention, what I claim as new, and desireto secure by Letters Patent, is

1. In a sitting device, the combination with a suitable support having acentral opening and a box mounted thereon over said opening and providedwith a suitable cover, of a cylindrical sifter arranged in said box andconsisting of circular end pieces, a wire screen surrounding and securedat its outer edges to said end pieces, means for journaling said sifterin the box and for rotating the same,

said sifter being divided longitudinally to form two sections, pinsprojecting from the outer faces of one of said sections, a rockshaftextendingoverand longitudinally of the other of said sections and bentto form a centrally-situated handle and hooks at its extremitiesextending parallel to the end pieces and adapted to engage the pins,longitudinally-extending wires or rods connecting said side pieces andarranged at the meeting edges of said sections, the adjoining edges ofthe screen being bent around the same, and strips secured upon theperipheries of said end pieces and extending over said rods and therock-shaft, said strips being bent around the rods and secured to themeeting edges of said end pieces, substantially as described.

2. In a sitting device, the combinatiomwith a suitable support having acentral opening and a box mounted thereon over said opening and providedwith a suitable cover, of a cylindrical sifter arranged in said box andconsisting of circular end pieces and a wire screen surrounding said endpieces, means for journaling said sifter in the box and for rotating thesame, said sitter being divided longitudinally to form two sections,pins projecting from the outer faces of one of said sections, arock-shaft extending over and longitudinally of the other of saidsections and bent to form acentrally-situated handle and hooks at itsextremities extending parallel to the end pieces and adapted to engagethe pins, longitudinally-extending wires or rods connecting said endpieces and arranged at the meeting edges of said sections, the adjoiningedges of the screen being bent around the same, and strips secu red uponthe peripheries of said end pieces and extending over said rods and therock-shaft, said strips being bent around the rods, secured atthemeeting edges of said end pieces and being provided with projectionsengaging said screen between the meshes thereof, substantially asdescribed.

In testimony that I claim the foregoing I have hereunto set my hand this15th day of September, 1898.
